Abstract

This document describes systems and process for forming processed slabs having embedded optical elements.

First claim

What is claimed is:

1. A processed slab, comprising:
a front major surface and a rear major surface, the front and rear major surfaces at least 2 feet wide by at least 6 feet long and extending perpendicularly to a slab thickness defined by a particulate mineral mix; and
a plurality of optical elements each having a first end, a second end, and a length between the first and second ends;
wherein all of the optical elements are surrounded by the particulate mineral mix between the first and second ends such that the entire length of each optical element is directly contacted by the particulate mineral mix.

2. The processed slab of claim 1 , wherein the optical elements allow transmission of light between the front major surface and the rear major surface.

3. The processed slab of claim 2 , wherein the optical elements comprise fiber optic cables.

4. The processed slab of claim 1 , wherein the front major surface comprises the particulate mineral mix and first ends of the optical elements.

5. The processed slab of claim 1 , wherein the optical elements are arranged such that the length of each optical element is parallel to the slab thickness.

6. The processed slab of claim 1 , wherein each of the plurality of optical elements is arranged within the processed slab according to a predetermined design.

7. The processed slab of claim 1 , further comprising a light source configured to transmit light between the front major surface and the rear major surface through at least one of the plurality of optical elements.

8. The processed slab of claim 1 , wherein the particulate mineral mix comprises quartz.

9. The processed slab of claim 1 , wherein the length of each optical element is equal to the slab thickness.

10. A processed article, comprising:
a processed slab having a front major surface and a rear major surface, the front and rear major surfaces at least 2 feet wide by at least 6 feet long and extending perpendicularly to a slab thickness defined by a particulate mineral mix;
a plurality of optical elements having a length between first and second ends; and
a carrier web connected to the processed slab at least partially by the plurality of optical elements;
wherein the optical elements are each attached to the carrier web in a fixed array proximate the first ends, and extend through the slab thickness;
wherein the carrier web is configured to be separable from the processed slab.

11. The processed article of claim 10 , further comprising a light source configured to transmit light through at least one of the plurality of optical elements between the first and second ends.

12. The processed article of claim 10 , wherein the processed slab comprises quartz.

13. The processed article of claim 10 , wherein the plurality of optical elements comprise fiber optic cables.

14. The processed article of claim 10 , wherein each of the plurality of optical elements are arranged within the processed slab according to a predetermined array.

15. The processed article of claim 10 , wherein the optical elements each extend completely through the slab thickness in a direction parallel to the slab thickness.

16. A process of forming a processed slab, comprising:
dispensing a particulate mineral mix into a slab mold;
positioning a plurality of optical elements within the slab mold;
contemporaneously vibrating and compacting the particulate mineral mix and plurality of optical elements arranged in the slab mold so as to form a processed slab that is generally rectangular and has a front major surface and a rear major surface; and
polishing the front major surface of the slab;
wherein the plurality of optical elements each have a length between first and second ends, and wherein each optical element is surrounded by the particulate mineral mix between the first and second ends such that the entire length of each optical element is directly contacted by the particulate mineral mix, and the first end is visible at the front major surface and the second end is visible at the rear major surface.

17. The process of claim 16 , wherein the plurality of optical elements allow passage of light between the front major surface and the rear major surface.

18. The process of claim 16 , wherein dispensing the particulate mineral mix is performed after the step of positioning a plurality of optical elements within the slab mold.

19. The process of claim 16 , wherein positioning the plurality of optical elements in the mold comprises inserting the optical elements into the particulate mineral mix within the mold.

20. The process of claim 16 , wherein the front major surface is defined by the particulate mix and first ends of the optical elements.

21. The process of claim 16 , wherein the length of each optical element is parallel and equal to a slab thickness between the front major surface and rear major surface.

22. A process of forming a processed slab, comprising:
dispensing a particulate mineral mix into a slab mold;
positioning a plurality of optical elements within the slab mold;
contemporaneously vibrating and compacting the particulate mineral mix and plurality of optical elements arranged in the mold so as to form a processed slab that is generally rectangular and has a front major surface and a rear major surface; and
polishing the front major surface of the slab;
wherein the plurality of optical elements each have a length between first and second ends, and wherein each optical element is surrounded by the particulate mineral mix between the first and second ends, and the first end is visible at the front major surface and the second end is visible at the rear major surface;
wherein positioning the plurality of optical elements in the mold comprises inserting the optical elements into the particulate mineral mix within the mold; and
further comprising inserting a projection into the particulate mineral mix to form a hole in the particulate mix, and wherein the step of positioning the plurality of optical elements in the mold comprises inserting an optical element into the hole.

23. The process of claim 22 , wherein the length of each optical element is parallel and equal to the slab thickness.

24. A processed slab, comprising:
a front major surface and a rear major surface, the front and rear major surfaces at least 2 feet wide by at least 6 feet long and extending perpendicularly to a slab thickness defined by a particulate mineral mix; and
a plurality of means for transmitting light between the front major surface and the rear major surface, the plurality of means for transmitting light being oriented parallel to one another, the plurality of means for transmitting light surrounded by the particulate mineral mix such that an entire length of each of the plurality of means for transmitting light between the front major surface and the rear major surface is directly contacted by the particulate mineral mix.
